HARVESTER.

SPECIFICATION forming part of Letters Patent No. 250,271, dated November29, 1881.

Application filed May 24, 1880. (No model.)

To all whom it may concern Be it known thatl, JOHN P. MANNY, ofRockford, in the county of Winnebago and State of Illinois, haveinvented a new and useful Improvement in Harvesters, of which thefollowing is a specification.

The present invention has reference more particularly to theconstruction and arrangement of the gear mechanism of a harvester, theobject being to combine compactness, simplicity, and strength.

The invention is fully illustrated in the accompanying drawings, inwhich Figure 1 is a perspective view of a one-wheeled front-cutharvester embodying theinvention, the platform being removed. Fig. 2 isa plan of a portion of the gear mechanism and of the parts immediatelyconnected therewith. Fig. 3 is a side elevation of the parts lying onthe stubble side of the vertical plane,indicated by the dotted line as min Fig. 2. Figs. 4 and 5 show the backing-ratchet by means of which themain gearwheel and the driving-wheel may be locked together, Fig. 4.showing the pawls and their springs seated on the face of thegear-wheel, and Fig. 5 the ratchet-teeth in the hub of thedriving-wheel.

Referring to these drawings more in detail, A represents the draft frameor pole of the machine. B is the main gear-frame; O, the driving-wheel;D,thegrain-wheel; E,the main gear-wheel; F, an inclined standard forsupporting the rake mechanism and mounted on the bracket G; H, therake-driving shaft supported on such standard, and I is a countershaft,and K crankshaft for driving the cutters.

The driving-wheel (J and the main gearwheel E are mounted upon the sameaxle,,and are made capable of being locked to each other, at the will ofthe operator, by means of an interposed clutch mechanism. The clutchmechanism here shownis a well-known form of backing-ratchet, operated bymeans of a shippingring, L, and being well known in the art does notrequire to be specifically described. It is plain that the pawls of thisclutch mechanism may be placed on either the gear-wheel or thedriving-wheel, as may be found most convenient, the ratchet element ofthe combination being, of course, placed on the other wheel. If the axlebe fixed in its bearings both wheels must be loose on the axle; but ifthe axle be free to turn in its bearings one of the wheels must be faston the axle. However the apparatus be built in this respect, the properadjustment of the shippingring will lock the two wheels together for theforward movement of the machine, or by the simple shifting of theshipping-ring the cutters will be permitted to remain at rest while themachine is advancing, and in either case the machine can be backedwithout revolving the gear-wheel and working the cutters. This capacityof the machine, however, being old in the art, is not claimed asspecially characterizing the present invention.

Upon the main beam of the gear-frame of the machine, which gear-frame isalso the main frame, is mounted the bracket G, and this bracket is soconstructed as to serve at the same time both as a bearing for the axleof the driving-wheel and as a support for the inclined standard F, whichis to carry the rake mechanism.

The main geanwheel E consists of an ordinary spur-wheel with abevel-face gear out upon one of its sides, the teeth upon its peripherybeing designed to mesh with the pinion upon the counter-shaft I, andthose composing the bevel-face gear meshing with the bevel-pinion on theinclined rake-driving shaft H. This form of gear-wheel, when used incombination with a counter-shaft and a rake-driving shaft geareddirectly thereto, enables these parts to be brought into comparativelysmall compass with great simplicity of construction and correspondingstrength, and by making the gearwheel and the pinions of these shafts tooverhang the main frame on the stubble side, as shown, the weight istransferred as far as possible to the driving-wheel, where it becomesefficient in securing the proper traction, and thus largely relieves theframe from the weight that would tend to sag it. This position of themain gear-wheel relatively to the main frame is secured without undulyincreasing the length of the axle by utilizing the backing-ratchet as adirect clutch mechanism between the driving-wheel and the gear-wheel.

The height of the finger-beam M is regulated as follows: The draft frameor pole is hinged to the forward end of the main frame, which latter hasthe capacity of rocking or vibrating form no part of the presentinvention.

on the main axle. Attached to the rear end of the draft-frame, at ornear to the hinge, is a post or standard, N, which is connected by anysuitable coupling-rod to the lifting-lever O, which lever is pivotedupon the rear of the main frame, and at as great a distance as possiblebehind the axle of the machine and still be within reach of the driver.By locating the post N close to the hinge between the draftframe and themain frame, the leverage of resistance, when it is desired to raise thefin gerbeam, is reduced to a minimum, and by placing the lifting-leverbehind the axle it results that when the driver pulls upon the lever toraise the cutters he at the same time necessarily pushes down upon therear end of the main frame, which will be found a more economicalexpenditure of power than if the'lever were mounted on the axle.

The lifting-lever may be provided, as shown, with the usual spring-pawland ratchet.

Neither the rake mechanism proper nor the platform is shown in thedrawings, as they These parts, however, are fully shown and described inother applications for Letters Patent filed contemporaneously herewith,and in which they are made the subject of special claims.

What is claimed as new is- 1. The combination, in a harvester, of a mainframe, an axle projecting over the stubble side thereof, a maingear-wheel mounted on the projecting part of such axle, between the mainframe and the driving-wheel mechanism, by which said gear-wheel isadapted to drive both the rake and the reel-bats, and backing-ratch: etsand shipping mechanism interposed between such gear-wheel and thedriving-wheel, for the purpose described.

2. The combination of the rake-driviu g shaft, the counter-shaftcarrying the gear for driving the cutters, and the main gear-wheelmounted on the main axle, and provided with both a spur-gear and abevel-gear for operating thev counter-shaft and the rake-driving shaft,substantially as described.

3. The combination, in a front-cut harvester, of a main frame whichrocks or vibrates about the main axle, a draft frame or pole hinged tothe front part of such frame, a lifting-lever mounted on the rear partof the main frame behind the axle, a rod or link connecting such leverwith a post mounted on the rear part of the draft-frame, at or near itshinge, and a drivers seat arranged in rear of the axle and at a point inadvance of the lifting-lever, substantially as shown and described.
